Air treatment and conveying system for air intake from traffic tunnels in offshore underground engineering

Abstract

The invention discloses an air treatment and conveying system for an offshore underground project utilizing traffic tunnel air intake, comprising a casing, the two ends of the casing are respectively provided with an air inlet and an air outlet, the casing is fixedly arranged on the lower surface of the traffic tunnel roof and the air inlet Adjacent to and facing the entrance of the traffic tunnel; there are two partitions I in the shell, and each partition I is vertically spaced and perpendicular to the direction of airflow, so that the inside of the shell is divided into three chambers, which are sequentially arranged along the direction of airflow. It is the first chamber, the second chamber and the third chamber, the first chamber and the second chamber are respectively the salt spray treatment chamber and the static pressure split chamber; the third chamber is horizontally provided with a partition II, The third chamber is divided into an air supply static pressure chamber and an air curtain static pressure chamber arranged in parallel up and down, and the air outlet is arranged on a housing corresponding to the air supply static pressure chamber. The system can not only provide fresh air treated with salt mist for offshore underground projects when the traffic tunnel is normally open, but also block the natural intrusion of outdoor salty air.

Description

technical field [0001] The invention belongs to the field of ventilation and anticorrosion of offshore underground engineering, and relates to an air treatment and delivery system for offshore underground engineering, in particular to an offshore air-conditioning system that utilizes salt mist filtration, air curtains and air-supply attached jets, and can guarantee indoor atmospheric corrosion levels of underground engineering The underground works utilize the air handling and delivery system for air intake from the traffic tunnel. Background technique [0002] The wall rock body inside the underground project emits radon and other harmful gases. At the same time, the equipment inside the underground project often emits a certain amount of heat when it is working. In order to eliminate harmful gases, remove equipment heat dissipation, and create an indoor air environment suitable for the operation of staff and equipment, it is necessary to introduce outdoor fresh air for ven...

Problems solved by technology

[0003] However, compared with inland areas, outdoor air contains a lot of salt spray in coastal areas, resulting in a higher level of atmospheric corrosion, and the corrosion rate of metals exposed to outdoor air increases significantly.
